I am trying to keep up on all the social advances. I am aware of the like button. I already have on my blog posts. However, I am thinking of adding to all my pages of my website. Do you recommend to do the same? If so, do you like 1 page for the whole site? How would you do it?
Also, do you recommend to set-up a facebook connect to login to your websites?
With facebook being 500 million users, I must consider all options. Any others to consider?
There are developer apps within Facebook that let you export the "like" button code and integrate it into your website. Not too sure about using an iFrame for for it, but it is a good way of keeping people informed of what you are doing.
I tend to use Facebook for previewing content and then redirect people to my website for the full version.
If you are going to use the Like button on every page, make sure you look at the open graph/social graph documentation as you should then be setting specific OG tags at the head of your page to distinguish between pages!
